triage

/TREE-ahzh/ noun, verb

1Sorting people or problems by urgency so the most serious get help first

Triage Meaning: Deciding Who or What Comes First

Law and societyNoun, verbMedicineUpdated 26 Oct 2026

The triage meaning, at its core, is sorting people or problems by how urgent they are, so that limited help goes first to those who need it most. In a hospital emergency department, triage is the first quick check a nurse does to decide how soon each patient must be seen.

The word has spread well beyond medicine. Support teams triage tickets, managers triage inboxes and governments triage budgets. Read on for a clear triage definition, a step by step picture of hospital triage, the colour tags used in disasters and the French word behind it all.

Triage meaning: two main uses

  1. Medical triage. The rapid assessment of sick or injured people to decide the order of treatment. It does not treat the illness itself; it decides who gets care first, and where.
  2. General triage. Any process of sorting tasks, requests or problems by urgency and importance. "We triaged the bug reports and fixed the three that crashed the app."

Both uses rest on one hard fact: there is not enough time, staff or money to deal with everything at once, so someone must decide fairly and quickly. That makes triage a practical answer to scarce resources, in the same family as good logistics.

How triage works in a hospital emergency room

When you arrive at an emergency department, a triage nurse usually sees you before any doctor does. A typical visit runs like this:

  1. Quick history. What happened, when it started, any key medical conditions.
  2. Vital signs. Pulse, blood pressure, breathing rate, oxygen level and temperature.
  3. Priority level. Many hospitals use a scale with about five levels, from "needs care immediately" to "can safely wait."
  4. Placement. The patient goes straight to a treatment bay, to a waiting area, or to a faster track for minor injuries.
Two people walk in at the same time: one with a sprained ankle, one with crushing chest pain. Even if the ankle patient arrived a minute earlier, triage sends the chest pain patient in first, because a heart attack is life threatening and a sprain is not.

This is why waiting times in an emergency room are not first come, first served. People are sometimes upset by this, but it is the purpose of the system.

Colour tags in disasters and mass casualty events

When many people are hurt at once, such as after a train crash or earthquake, responders often use simple coloured tags so everyone can see a patient's priority at a glance. Exact systems vary by country, but a common pattern is:

TagMeaning
RedImmediate: life threatening but likely to survive with quick care
YellowDelayed: serious but stable enough to wait a short time
GreenMinor: walking wounded who can wait longer
BlackDeceased, or injuries so severe that survival is not expected with the resources available

The black category raises real ethical questions, which is why disaster triage rules are written in advance and staff are trained to apply them consistently. For related ideas about fairness in hard choices, see ethics.

This section describes triage in general terms. It is not medical advice. If you or someone near you is unwell, contact local emergency services or a qualified health professional.

Triage outside medicine

  • Tech support: an IT team triages incoming tickets into critical, high, normal and low.
  • Software: developers hold bug triage meetings to decide which defects to fix first.
  • Email and work: "I spend the first twenty minutes of the day triaging my inbox."
  • Policy and money: a city facing a budget shortfall might triage its repair projects, fixing the most dangerous bridges first.
  • Home life: parents triage chores on a busy morning: lunches packed, homework found, the rest can wait.

Origin: from sorting coffee beans to sorting patients

Triage comes from French triage, a picking out or sorting, from the verb trier, to sort or cull. English used it from the early 1700s for sorting goods by quality, and later for the lowest grade of something, such as the poorest grade of coffee beans left after sorting.

The medical sense grew out of military medicine. Surgeons in the Napoleonic era already sorted the wounded by severity rather than rank, although they did not call it triage. The word itself was applied to casualties by the French army during the First World War, where sorting stations were known as salles de triage, and English speaking armies soon adopted it. Today the medical sense is the main one.

Using triage correctly in a sentence

As a noun: The patient was assessed at triage. Triage took less than five minutes. As a verb: The nurse triaged six patients in the first hour. We need to triage these complaints. Pairings include triage nurse, triage desk, triage system, triage level and first stage of triage.

Do not confuse triage with treatment. A patient who has been triaged has been assessed and placed in a queue, not cured. Also note that the word does not mean simply "to help"; it always involves ranking. Our law, politics and society hub holds more vocabulary from public institutions, while the urgent sense of acute often shows up beside triage in medical notes.

Frequently asked questions

How would you define triage for someone new to the word?

Triage is deciding the order in which people or problems get attention, based on how urgent each one is. The most serious cases go first.

Is triage a noun or a verb?

Triage happily plays both roles. You can say "the patient is at triage" and "the nurse will triage you." The verb forms are triaged and triaging.

How do you pronounce triage?

Most people say TREE-ahzh, with the ending like the end of garage. A smaller group says tree-AHZH, landing on the end.

Why did someone who arrived after me get seen first?

In emergency triage, order depends on how serious a condition is, not on arrival time. A person with a more urgent problem will be called ahead of someone whose condition can safely wait.

What is a triage nurse?

A nurse trained to assess patients quickly when they arrive, measure their vital signs and assign a priority level. They may also start simple measures such as pain relief or tests.

What does triage mean at work?

In offices it means sorting tasks, tickets or requests by urgency and impact. It is informal but widely understood.
